' Patented Feb. 6, 1912.: Serial no. 603,139.

To all whom it may concern section through the the bowl of the Be it known that LALBERT S. SPEIRs, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented .a new and useful Pipe-Co,ver, of which the following is a specification. i

This invention relates to covers for the bowls of tobacco pipes and is more par ticularly an improvement upon. the structure disclosed in Patent No. 838,5934issued tome on December 18, 1906;

The principal object of the .present in vention is to provide a cover designed to prevent tobacco from being blown out of pipe or becoming otherwise accidentally constituting a tamping device by means of which the tobacco can be pressed down into the bowl.

Another object is toprovide'adevice of this character having improved means for holding it in position upon the bowl of the pipe and which is simple and inexpensive in construction and can be quickly applied to or removed from the pipe."

With the foregoing and other objects in view which 'will appear as the description proceeds, the invention resides in the.con1- bination and arrangement of parts and in the details ofconstruction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made v within the scope of what is claimed 71thout departing from the spirit of the invention. f

lin the accompanying drawings the preferred form of the invention has been shown.

In said drawings :F1gure 1 1s a plan view of a pipe bowl having the cover ap- 2 is a central vertical plied thereto. Fig.

4 vis a perspective View of the band of the cover. Fig. 5 is a detailview of the spring screen of the cover. Fig. 6 is an enlarged section through one end portion oftne band and spring and showing the means employed for connecting the two together.

Referring to the figures by characters -'of' reference 1 designates a substantially circular band of spring metal having out gage.

said button being displaced, said means also over the spring or standing ears 2 at the terminals thereof and extendingfrom the upper edged the band, each of these ears being provided with an upwardly extending outer end 3 constituting a finger piece. Another ear textends radially from theiupper edge of the band, at a point preferably equidistant from the ends of the band. These ears have prongs 5 struck downwardly therefrom and engaging the-outer convolution of a coiled spring 6 preferably formed' of .wire of a small The innermost convolution of the spr ng is attached over one or more of the inner convolutions, indicated at 7. The outer convolution of the spring is 1 preferably clamped against the lower faces of the ears 2 and 4 by pressing the prongs 5 upwardly thereagainst. Moreover, as shown in the drawings, the outermost convolution of the spring is arranged outside of the band 1 whereas the remaining convolutions are dis- In using the device the finger pieces 3 to a button extending I are drawn toward each other so as to con- 8 tract the band and the spring attached thereto. The said bandis then inserted downwardly into the bowl of a pipe until the cars come intov contact with the open end of the bowl, whereupon, by releasing the finger pieces, the bandwill spring back automatically and frictionally engage the inner surface of the pipe bowl. The cover will thus be held securely in position, and

cannot become accidentally detached. Morecoil constitutes an efli-- cient screen for retaining the tobacco without however interferingjvith the free escape of smoke from the bowl. Whenever it isdmired to tamp or press down the tobaccov contained within sary to press the button 7 the tobacco, as indicated Fig. 2.

downwardly onto by dotted lines in It will be seen that the device isvery simple in construction, cheap to manufacture, and. when applied to a pipe, it does not detract from its appearance, but constitutes an ornament. A What l's'claimed is 1- An attachment for tobacco pipes, including a spring gripping element insertible'into the bowl of a pipe-and expansible the bowl, it is merely necestherein to engage the bowl throughout the length of said element, a screening member carried by said element and secured thereto, and means for contracting the gripping element 'to' disengage it from the bowl.

. 2. A tobacco pipe attachment including a member insertible into the bowl of the pipe and expansible to grip the bowl throughout the length of the member, means outstanding from said member for bearing on the bowl to support the member within'the bowl, a screening device carried by said member, andfinger pieces projecting from 'the terminals of said bearing means.

,3. An'at-tachment for tobacco pipes, including a spring gripping element insertible into the bowl of a pipe and expansible therein to engage the bowl,throughout the length of said element, a obiled spring having its other convolution connected directly to said element, and means extending from opposite portions of saidelement for contracting it and the spring.

4. A tobacco pipe attachment including a gripping member insertible into the bowl of a pipe and expansible to engage said bowl throughout the length of the member, an elastic screening element carried by said member and secured thereto, and means for contracting said member and spring to disengage the member from the bowl.

5. An attachment vtor tobacco pipes, comprising a spring band insertible into the bowl of a pipe andexpansible 'to engage the bowl throughout the length of the band, a screening device carried by the band, and means for contracting the band and screening device to disengage said band from the bowl.

6. An attachment for tobacco pipes, comprising a band of spring material having normally spaced terminals,said band being insertibleinto the bowl of a pipe and expansibl e to engage the bowl throughout the length of the band, supporting projections outstanding from the band, a spiral spring constituting an elastic screen, means upon the projections for engaging the spring -to bind it directly upon. the band, and means for contracting the band and spring.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
